Problems solved by technology

[0004] 1. Due to the complex sea conditions, long journeys, and large operating depths encountered by large-scale deep-sea oil exploration projects, the supply ships currently serving the platform are obviously too small in transportation capacity, low in efficiency, and high in cost
[0005] 2. Ordinary large cargo ships have poor maneuverability, low speed, do not have dynamic positioning capabilities, cannot meet the transportation needs of various goods working on offshore platforms, and do not have the ability to load and unload cargo at sea

Embodiment Construction

[0021] refer to figure 1 , a passenger and cargo logistics support ship for an ocean engineering base, including a bow 1, a midship 2, and a stern 3, the bow 1 is a forward-inclined nose bow, and the midship 2 of the ship is a fat ship shape with a large square coefficient , the stern 3 is an inwardly rotating fin tail, and the inwardly rotating fin tail is in the shape of a short tail and inwardly rotating tunnel. This shape improves the hull efficiency by 2.0%, reduces the appendage resistance by 8%, improves the fast performance of the ship, and reduces Reduces energy consumption; using the characteristics of the internally rotating fin tail, the diameter of the propeller can be increased, the speed of the propeller can be reduced, and the pre-swirl and false tail effects are generated. The tail wake is very uniform, and the propulsion efficiency is improved by 15-25% Vibration and noise Greatly reduce, reduce and reduce noise; the ship has four sets of independent propulsi...

Abstract

The invention discloses a large logistics support boat for an oceanographic engineering base, which belongs to the technical field of boats and comprises a boat head, a boat middle and a boat tail, wherein the boat head is a forwards inclined type nose head, the boat middle line form of the boat is a large square factor fat boat ship, the boat tail is an inwards rotating fin tail, and the inwards rotating fin tail is in a short tail inwards rotating channel type shape. The boat has the advantages that the cargo transportation capability is high, the efficiency is high, the speed is high, and the motive power positioning capability is realized.

Description

technical field [0001] The invention relates to a large logistics supply ship for transporting personnel in an ocean engineering support base, and belongs to the technical field of ships. Background technique [0002] The transportation of maritime logistics support materials is generally carried out by special working ships such as helicopters, three-purpose working ships, and platform supply transport ships. Most of these transportation methods are based on the working mode centered on a single ocean platform. [0003] As the number of offshore transportation platforms increases and their distribution becomes denser, a certain scale has been formed. The working mode of regionalized system using the base as the center is being explored. The base is equivalent to a large sea passenger and cargo transfer station, with facilities such as warehouses and personnel rest areas. The oil, water and other goods needed on the platform and the platform staff can be transported to the...
